The photovoltaic system generates energy for the electrical consumers. The electrical consumers to be supplied by the photovoltaic system are defined on the System selection page.

The simulation calculates the PV yield using the calculation kernel from the partner software PV*SOL.

How to configure systems with photovoltaics:

Selection

1. Select a PV module. There are three modules available with different efficiency and different power to choose from.

2. Specify the number of PV modules. The total gross area and the total power will be displayed.

Lineup

3. Specify the alignment of the PV modules. The azimuth is displayed accordingly. In the northern hemisphere, the azimuth corresponds to 0° = south.

4. Specify the setup angle of the PV modules.

Control

The self-consumption share and the degree of self-sufficiency can be optimized via the control system. The aim of the optimization is to increase the period between the reheating processes. This increases the probability that in the meantime, yield is generated via the PV modules, which can then be used for reheating.

5. When Raising the storage tank temperature is selected, the storage tank temperature of the existing storage tanks is raised to the maximum flow temperature of the heat pump.

6. When Lowering the storage tank temperature is selected, the storage tank temperature of the existing storage tanks is reduced by 5°C if there is no hot water demand.
